* layout.cc (Layout::get_output_section): Add is_interp and
is_dynamic_linker_section parameters. Change all callers. (Layout::choose_output_section): Likewise. (Layout::make_output_section): Likewise. (Layout::add_output_section_data): Add is_dynamic_linker_section parameter. Change all callers. * layout.h (class Layout): Update declarations. * output.h (class Output_section): Add is_interp, set_is_interp, is_dynamic_linker_section, set_is_dynamic_linker_section methods. Add is_interp_, is_dynamic_linker_section_ fields. Change generate_code_fills_at_write_ to a bitfield. * output.cc (Output_section::Output_sections): Initialize new fields. (Output_segment::add_output_section): Add do_sort parameter. Change all callers.
